.To all whom it may concern:

Be it known that I, WELLiNGToN PARKER. KIDDER, of Boston, in the countyof 'Suolk `and State of Massachusetts, lieve invented e 5 new and usefulImprovement in Type-Writx5 Fig. 3 is a. partial rear elevation showingmore particularly the mechauismfor effecting the vertical shift of thepaper4carringe; Figs. 4, 5, 6,'end '7, details showing the movable wingsfor side guides to the ends of the A type-,bars at the printing-pointand 'a part of the escepemeni'. mechanism. Fig. 8 is a. perl tial planof Athe rocker-shafts vend carriageactuating mechanism. Fig. 9 is an endelevation of what is shown in Figs with the type-ba.' supporting plateadded end shownormal position. Fig. 10 is e. similar view, except thatthe type-ber is forward to the printing-pointnnd has actuated one of the30 rocker-ehefts to operate the pawl of the escapement mechanism. Fig.1l is a sectional view more clearly showing linking mechanism. Fig'. 12is s. partiel elevation of the paper-cnrriage'mounted upon rollers.`Fig. 13 is e. section on line 17 17 of Fig. 12.

My improvements apply to thst class of characters are placed on the endsof the slid ing bars, radially mounted to deliver impressions at e.common printing-point by endthrust. By placing all type-bers in a singleand.- preferably horizontal piene' and by at taching the key-leversdirectly to the bsrs withoutintermediate mechanism, and, further, byattaching two or more characters to each t'ypefhar, thereby greatlyreducing the number of keys and typefbars inmschines of a. given numnerof. characters using efyerticel shift for the pepercerriege, I am chieto s. machine of much grester siniplic'ity, less expensive, morecompnet, and

vinovrtble wings E E',

yet admitting the vinnxirnum of speed and utility;

I will now describe the parts and movements of my machine.

Are'presents the fratrne, andA the base.

B B B are three curved supports-for the pivots of the threehanks ofkeylevers. The

vends of these supports are fast to the frame A. The supports aregrooved B and slotted 6o B2 to receive the pivots Ba of the key-leversB4. Each'key-lever is providedwith a. nger button or surface B5 onits'neerly-horizontal arm b, `While its nenrly-vertical arm, lbent atitsnl'cwer end to e. right angle, passes through or engages a'slotBfor'med in type-bar B7."

At 'the forward ends of type? bnrs B7 ere attached two or moretypecharecters B8, in this instance three characters to each bar. Aninclined surface Bs-is'formed on the under side of catch -type-ber togive motion to the escgpelnent mechanism-cow e 475 mon to eil of thekeys for feeding' the peperf' carriage D and also Ito give-motion vtolthe the letterv being side' guides to the type characters at theirpri-'nting-peiht. These wings E and E' in their positi :i of rest ere asindicated in'Figsvl'and s, end are pivoted in frame A at assud a4.Eccentricelly attached at a5 are connectingrocker-shafted", pivoted inthe frame. l It will be noticed 'that there are two independentrockersheits a placed in a. line with -eacli other, their inner journalsmeeting in a. common bearing in the center of the machine et ctw, Fig.4. Fast in each shaft arethe curvedzgo' rods alherigaged by the infclnesBil on the?l under sides of the type-bars B. VMotion is 'when e; keyonthet'side of the machine isop ereted.' :The other rocker-shaft Q9. isOperated only by the keys ofthe cther'sideor half of pivoted to leversa7 and as, fast on .imparted tov .one of these rocker-shafts aon'ly- IOO65 known escapernent icommon use.

I in common use n n-other typewriters and too i .well known to requiredescription. 'There'- turn rockin motion of shafts a9 and lever di?is'eeeted y'any convenient arrangement of springs,'as w15.

le' It will be seen that to simplfv-etectthe feed of the paper-carriageno necessityfexists for making two independent shafts' a9; but I utilizethese two shaftsto operate the movable W .I 'wings orside guides E'andmEQ which I will now describe.

Side -gnide'sto the type ends B. of the bars B7-at or near the point ofimpression are nec? essary to deflect the type from ,the longitudinaldirection of thevbars in their various ane'e. gies to a direction atright-"angles to the snrfaceof the paper to beprinted. Such guidesmightloe rigidly fixed to the fraineA but this would cansethcbars at theentremesidesof the 'machine 'to enter between the guides with too A muchfriction on account of "the steep any gles of contact-as, for instance,dotted typehar 3 in Fig. moving in the direction of ih e .'ar'row sagainstv guide E, striking its surface at ltoo, v.nearly a right angleto be easily dego iliccted in thedirection of arrow 5 between l lthefgnides Ell' to the impressionon line '6.

To remedy this, wheneverabar on-one side of Athe machine, as bar 3, inFig.4 4, is ystruck the guide E ofthe opposite side is swung for- .35ward to aposition at or neara right angle to the siirface of the paper,as shown in dotted lines in Figi 4, thereby oering a comparativelyeasynclined surface to the type, wherehyit is deflected directlyto-theimpression,

4o- 'vvhich is at vline 6. In like manner whenever .'a keyof the'opposite half of t-hev machine is struck the other guide E is swungforward. These movements are accomplished by one of A'the links a6,connecting guide E of one side with levery (1F-.of rocker-shaft 0.9 ofthe opposite side of the machine, and the other linka6 vice versa, thetwo links in crossing each other being properly)1 odset to pass Withoutinterference. It is evident that the normal posi- 5o tion of these wingsmight ybe closed instead =of open, as shown, andthe mechanism ar rangedto open eiiheiffof them out of thepath of ,an approaching type-har, asrequired, or, :instead of swinging, they might be moved 5 5into'osi'tion in a variety of ways, all of which wonl `constitute a partof "myinventiom My new vertical shift paper-carriage consists of asliding or moving frame D', mounted ori rollers or, in slides D2 on thebase A.

'6o To this frame may be attached an 'ordinary cord D3, leading to adrum" D5, provided with the usual' coil-spring Dfo'r drawing thecarriage; also with -the usdal fast and loose racks C, engaged' by thelpani al?, forming the Well- Standing pright and fast in the movingframeD naar its opposite' ends are the two racks D4,

which also serve .asfguide-posts to a second frame d, carrying thevpaper-roll dwith clam p1 platedz, between which platefand rollthe paperis secured 'in the usual manner to receive its impressionsfromiyilQ-hars. Jonrnaled .in

the ends of the secondary or upper frame-d5- `is freely mounted the.shaft da, to which are fast two pinions or gears di, engaging thenpright rack-posts D4. The object of therack,

gears, and shaft is simply to keep-the framed in a parallel position asit is moved vertically up and down on the guide-posts D5.,

This vertical shift of the frame d, carrying the' paper-roll ol', is forthe purposev of presenting the line on the paper to be printedto eitherof the three characters 138v of type-hars B7, and corresponds to thehorizontal shift on ordinary `typedever machines. It is accomplished asfollows: A path d5 isV formed in'the carriage-frame d', which receivesthe frictionroller d, pivoted` on studd?, fast on one end ofrocker-shaftd,joi1rnaled in base of frame A. The opposite end ofrocker-shaft dire` ceives the double-armed levers d10 du, provided -withn'ger buttons o1 surfaces for use similar i to the key-lever buttons Bior other arrangement of d10 and d maybe substituted. The under, snrfaceof the lever dsfis for-ined with two bearers al12 clfresting againstlthefirm pressnre of aspiring d,supported at its ends d on base A". Thenormal Yertical position of the carriage d. is shown in the drawings,both feet or points d12 el13 of lever d8 resting on the spring d1",supporting the printingpoint on` the roll d opposite the central tynecharacters B8 on the type-bars B7. Depressing thev lever d10, rockingthe shaft di. raises the friction-m11 d, as indicated in doue. 1in-@s inFig. 3, depressing the spring d, as indicated. In like manner if leverdu be dcpressed roll d6 is carried belowthenormal positioinas indicated,also depressing spring all", in either case acting in path d5 to raiseor lower the paper-carriage d to either the upper or lowerV typecharacters Bs l of the .type-barB",

vthe springd returning the carriage to the normal position whenever thekey d or d10 is released. 'Any suitable stops, as die andai,A

may he provided tollimit the vertical motion of the carriage in eitherdirection. In some cases I' intend to neutralize the dead-weight ofithe. 'earriaged and roll d by springs or connteraveights, in order thateither shift-keV d10. or d maybe operated with equal facilitp'f'. rlhismay be accomplished by a spiral spring 0.1.8, attached to cords di andd20, led over friction-pulleys d, mounted onv studs 22, fast in upperends of racks or guide-posts D, the

A convenient fol-m Aof inning mechanism" consists of spoolsl and 2,joiilrnaled in brach@A ets 8, fast to the franie of the machine. The

ink-ribbon 4. leads from one spool to the other over suitable" guides 5,passing 4between the inner-ends of. the' type-bars and the platen. Roll1 is provided'with a ratchet-WheelV-with which engages a pawl 7,monnted'on an arm 8, Afast on rocker-shaft et. Spool 2 is provided witha ratchet-wheel 9, with which engages a pawllO, mounted on an arm 11,fast on rockerr` When the rocker-shaft is actuated, pawl turnsratchetavheel 9, feeding spool 2 one notch. When all the ribbon has beenwound on spool 2, spring 12, pivoted at 13 to the base of the machine,is swung ont of engagement with the pawl, which then ldrops out ofengagement with the ratchet-wheel 9, and pawl 7,until now kept ont ofengagement with ratchetavheel 6, is allowed to drop into engagement withratchet-wheel 6 by remov'- ing the supporting-pin 14. The ribbon is newrewonnd on spool 1.

To insure alignment, the inner ends of the type-bars are supported onaguide-plate 15 atthe time the impression is taken, plate 15 .beingsupported by the frame of the machine. s the type-levers are movedendwise forimpressionthey preferably slide overthe plate 15.

I claim-l s l 1. In a typewriting machine, the combina tion of sideAguides E and E and` links a6 with levers a7 and as and roeker-shaftsa9, the links connecting the levers with the guides and the levers beingmounted on the rocken shafts to actuate the guides, substantially as setforth.
